Installing .NET 5.0 on Raspberry Pi 4

None of the official methods worked for me (not even involving horrid fixes ;)). So I ended up going the super manual route (mostly copying https://elbruno.com/2019/08/27/raspberrypi-how-to-install-dotnetcore-in-a-raspberrypi4-and-test-with-helloworld-of-course/ and https://elbruno.com/2020/01/05/raspberrypi-how-to-solve-dotnet-core-not-recognized-after-reboot/).

; OK, it's 64bits
; Get Arm64 download URL from https://dotnet.microsoft.com/download/dotnet/5.0
$ mkdir temp && cd temp
$ curl [URL] --output [FILENAME]
$ mkdir $HOME/dotnet
$ sudo tar zxf [FILENAME] -C $HOME/dotnet/
$ sudo ln -s $HOME/dotnet/dotnet /usr/local/bin
$ dotnet --version

; or whatever version you downloaded
; Now we need to add it to PATH. Add the exports
$ sudo nano ~/.bashrc
export DOTNET_ROOT=$HOME/dotnet
export PATH=$PATH:$HOME/dotnet
export PATH=$PATH:$HOME/.dotnet/tools
; then Ctrl+X to save and exit. finally, load the new exports
$ source ~/.bashrc
